The scientist used the Law of Conservation of Mass, which states that mass is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants (6.7 grams of nitrogen gas and 19.3 grams of hydrogen gas, totaling 26 grams) must equal the mass of the products; thus, they predicted the formation of 26 grams of ammonia.
N2+3H2−> 2NH3
Nitrogen gas ( N2
) reacts with hydrogen gas ( H2
) to form ammonia ( NH3
), a well-known cleaning product present in many households. A scientist adds 6.7 grams of nitrogen gas to 19.3 grams of hydrogen gas to start the reaction. In this reaction, all of the nitrogen and hydrogen react. Before running the experiment, the scientist expected the products of the reaction to be a total of 26 grams of ammonia. In 1-2 sentences, explain the law that the scientist used to predict that the product of the reaction would be 26 grams of ammonia.

can it be shorted to one sentence pls and make it look like a 8th grader
The scientist used the Law of Conservation of Mass, which says that the total mass of the reactants should equal the total mass of the products, so they expected to make 26 grams of ammonia from 26 grams of nitrogen and hydrogen.
